Engineering Technician I/II

Effective: 7/01/08
Range: I = G-56 / II = G-64
Respirator Class: 3


Perform routine and journey level AM/CADD drafting and Geographic Information Systems (GIS) data entry work and computations relating to pipeline mapping and drawing; civil, structural, mechanical, and electrical engineering; perform related work as required.

Distinguishing Characteristics

Engineering Technician I

This is the entry-level class in the technical engineering series. Incumbents of this class perform routine office and field engineering work that does not require previous specialized experience. Generally, work is observed and reviewed both during performance and upon completion, and changes in procedures or exceptions to rules are explained in detail as they arise.

Engineering Technician II

An Engineering Technician II works under general supervision and is expected to perform moderately complex procedures in carrying out a variety of office and field engineering work. Work in this class is distinguished from that of the Engineering Technician I class by the greater independence with which an incumbent is expected to operate.

Supervision Received and Exercised

Receive general supervision from higher-level engineering personnel.

Examples of Essential Duties

Duties may include, but are not limited to, the following:

  • Compile and revise as-built drawings.
  • Perform varied and complex drafting, mapping and GIS data entry work related to collection and recycled water system maps and facility drawings in support of civil, structural, mechanical and electrical engineering.
  • Perform design drafting for collection system, recycled water system and treatment plant projects; file, revise, maintain and retrieve a variety of engineering drawings, maps, documents, and records.
  • Research records for information to develop, revise, and draft accurate treatment plant, recycled water and collection system plans and maps and resolve conflicting data.
  • Post-tentative jobs and other information onto manual and AM/CADD drawings.
  • Check parcel maps, subdivisions, and various other drawings to ensure conformance with State Subdivision Map Act, District policies, and engineering correctness.
  • Prepare and draft easement plats, survey, boundary and topographical maps, mechanical drawings, and project plans from field and survey notes, legal descriptions, and other sources.
  • Use computers, AM/CADD software, calculators, drafting tools and equipment, reproduction equipment and a variety of engineering and office equipment.
  • Review and check the work of peers.
  • Research, compile and communicate information to staff and other public agencies regarding engineering drawings and possible construction conflicts.
  • Perform and review mathematical calculations requiring algebra, geometry, and trigonometry.
  • Make or request field surveys to verify as-built discrepancies and locations of existing facilities; assists in conducting, tabulating and analyzing various engineering surveys. Calculate distances, ties, angles, and closures.
  • Assist at permit counter as needed.
  • Assist on field survey crews as needed.
  • Review and gather data, legal descriptions and documents relating to easements, rights-of-way, ownership, restrictions, zoning and other property rights.
  • Assist in preparing layouts and designs for service mains; prepare and update standard drawings, specifications, base maps, and as-built drawings.
  • Prepare a variety of graphic presentations, displays and special maps for meetings.
  • Perform related duties as required.
